I don't like calling people out or calling people names but this moment deserves it
Anybody that is happy about the nerf this early in the game's life is retarded.
No not because it is or is not justified, because NRS is implying that MK9 is dictated to go a certain way, and that players should not even be given the time to possibily develop either the skills or the strats to adjust to the game.
Most GOOD gaming company that makes patches, do so by atleast weeks if not months of observation, and especially not in the first month of the game release (excluding game breaking scenarios).
edit
I guess it would be unfair to make the statement that only good gaming companies do things XYZ way.
I'll be ok to demand a tweak if lets say Kung Lao had a, lets say, stupid 70% easy combo with 1 meter that he could do anywhere on screen and easy setup. Ok that's broken. But as of right now? is he really strong? yes. Is he over represented compared to the rest of the cast? At the moment you could say so. But is he at the point where 80% of matches are KL mirrors solely because he is the only viable character? No
